THE cost of keeping police round the clock outside the Ecuadoran embassy in London in case Julian Assange emerges has hit $4.37 million, British police said.

Officers have been stationed outside ever since the Australian-born WikiLeaks founder Julian Assange jumped bail and fled there on June 19 after losing his battle in the British courts against extradition to Sweden, where he faces questioning over allegations of rape and sexual assault. Ecuador has granted Julian Assange political asylum.

Scotland Yard police headquarters estimated the total cost to the end of January in salary and for the officers stationed on duty and the rest in overtime payments.

Assange, a 41-year-old Australian former computer hacker, founded the WikiLeaks anti-secrecy website which enraged Washington by releasing cables and war logs relating to the wars in Iraq and Afghanistan in the biggest security breach in American history.

A spokesman at the Ecuadoran embassy said: ``The Ecuadoran government is concerned by the significant cost to the taxpayers of London of policing the embassy.

"However, we believe this expenditure could be avoided if the UK government would provide the undertakings that the Ecuadoran government has sought that there will be no onward extradition of Julian Assange to the United States.

"The Home Office (Britain's interior ministry) has the power to offer such an assurance but has so far declined to do so.
